Accessing IMAP through an http proxy works, albeit often fails. I use this 
setup at work where accessing external IMAP from internal network is not 
possible.

I can escape corporate network through corporate http proxy, either by setting 
up a systemd socket (then IMAP server must be configured to connect to a local 
port).

A mote practical solution is to setup  proxy in system-settings and set the 
"use this proxy for all protocols" checkbox.

Unfortunately, this is not reliable and I have to restart akonadi once or 
twice a day. That said, I can tell if the reliability problem comes from 
akonadi or from the corporate proxy.
